5(6)-TAMRA, SE

AKA: 5(6)-Carboxytetramethylrhodamine, succinimidyl ester [NHS-Rhodamine]
Formula Weight CAS#
C29H25N3O7 527.53 246256-50-8

5(6)-TAMRA, SE is an amine-reactive orange-fluorescent dye for synthesis of orange-fluorescent biomolecules. This dye has been widely used in preparing fluorescent peptides, proteins, nucleotides, oligonucleotides, and enzymes. 5(6)-TAMRA, SE may be reacted with amines on peptides, proteins, modified nucleotides, biopolymers and other amine-containing biomolecules to yield a robust amide linkage. The absorbance spectrum of some TAMRA conjugates may be dependent on the degree of labeling density and dye-dye interactions, but the fluorescence is insensitive to environment pH and is relatively photostable. Conjugates of 5(6)-TAMRA are excited near 547 nm with fluorescence emission near 576 nm.
